Abstract
Experiments were performed on 13 Wister rats. Fastblus (FB) was injected into subcutaneous tissue in perineum area and nuclear yellow (NY) was injected into subserous lamina of the bladder wall, respectively. FB, NY and FB+ NY were mostly found in the spinal ganglions of L6, S1 ans S2 segments. The numbers of FB, NY and FB+ NY labeled cells were 146, 186 and 81, in a total of 463 labeled cells and their proportion was 40%. 51% and 9%, respectively. The result indicates that the spinal ganglion neurons dually innervate both the somatic and visceral tissues, and the convergence of somato-visceral sensory pathways might occur in the spinal ganglion cells.
